As everyone knows, after announcing my retirement from Formula One last year, I agreed to return this season to help Williams when the call came. I have now enjoyed four great years with the team, but my career in Formula One will finally come to an end this season. Once more, I would like to say a big thank you to everyone who has supported me throughout this time: my wife and my father, my whole family, my manager Nicolas and all my friends, colleagues and sponsors. I would also like to add a huge thank you to all of the fans who have been incredibly supportive and passionate over the years. I take so many great memories with me as I prepare for my final two races in Brazil and Abu Dhabi, and although they will be emotional, I am looking forward to ending on a high note and preparing for a new chapter in my career.
